ONE-HALF TO CLYDE M. METTLER, OF ST. LOUIS, MISSOURI.

INTENSIFIER.

Application filed May 17,

T 0 all whom it may concern:

Be it known that 1, CHARLES SMITH, a citizen of the United States, residing at St. Louis and State of Missouri, have invented certain new and useful Improvements inlntensifiers, of which the following is a specificaticn, reference being had therein to the accompanying drawing.

My invention relates to improvements in intensifiers and has for its object to provide a conducting element leading to the spark-plug, and composed of a mass of comminutedmetallic particles which may be commingled with pulverized carbon and glass, said mass being confined in a nonconducting receptacle and serving to convey the electric current.

The drawing is a longitudinal vertical view in mid-section of a device embodying my invention.

I have illustrated the receptacle 1 as a glass tube containing a mass 2 of comminuted materials which mass will be herein after more particularly described.

The heads 3, of copper or like conducting material form closures for the receptacle 1, and each head 3 has an integral projection i terminating in the eye 5.

Outside the heads 3.the tube 1 is filled with a mass 6 or" non-conducting plastic material which has integral lugs 8 extending into apertures in the tube 1 to hold said lass 6 against accidental displacement. The

mass 2 comprises metallic filings preferably mixed with pulverized carbon and glass, and its particular metallic particles and carbon and glass content may be of various propor- Specification of Letters Patent.

tions. In practice I have made up the mass 2 as follows; of brass or copper filings by bullr; of steel or iron filings 25% by bulk; of nickel filings 2% by bulk; 0:5 silver filings, carbon particles and pulverized glass 1% of each by bulk.

The passage of the electric current through this mass has an intensifying efi'ect like that of the ordinary spark-jump, and the electric current still further comminutes and diftuses the carbon particles throughout the mass with the result of increasing the intensifying action.

' Having thus described myinvention,what I claim as new and desire to have secured to me by the grant of Letters Patent, is-

1. In an intensifier a non-conducting receptacle having closures of conductive material; and a mass of comminuted conductive material held in place within said receptacle.

2. In an intensifier, a non-conducting receptacle having closures of conductive material; and a mass comminuted conductive material held in place within said receptacle, said mass comprising metal particles mingled with pulverized carbon and pulverized glass.

3. In an intensifier, a tubular container; heads of conducting material forming closures for said container, and having integral projections; and a mass of comminuted materials comprising metallic, carbon and glass particles held in place within said container and filling said container.

In testimony whereof I hereunto alfix my signature.

CHARLES SMITH.
